1. What are the assumptions for conducting a paired or dependent samples t -test in a study? Which of these assumptions do you think were met by the Lindseth et al. (2014) study?
2. In the introduction, Lindseth et al. (2014) described a “2-week washout between diets.†What does this mean? Why is this important?
3. What is the paired t -test value for mood (irritability) between the participants ’ consumption of high- versus low-aspartame diets? Is this result statistically signiï¬cant? Provide a rationale for your answer.
4. State the null hypothesis for mood (irritability) that was tested in this study. Was this hypothesis accepted or rejected? Provide a rationale for your answer.
5. Which t value in Table 2 represents the greatest relative or standardized difference between the high- and low-aspartame diets? Is this t value statistically signiï¬cant? Provide a rationale for your answer.
6. Discuss why the larger t values are more likely to be statistically signiï¬cant.
7. Discuss the meaning of the results regarding depression for this study. What is the clinical importance of this result?
8. What is the smallest, paired t -test value in Table 2 ? Why do you think the smaller t values are not statistically signiï¬ cant?
9. Discuss the clinical importance of these study results about the consumption of aspartame. Document your answer with a relevant source.
10. Are these study ï¬ ndings related to the consumption of high- and low-aspartame diets ready for implementation in practice? Provide a rationale for your answer.
